Re:   Opinion of Counsel regarding the Registration Statement filed on Form N-14
      under the Securities Act of 1933 (File No. 333-134486)

Ladies and Gentlemen:

We have acted as counsel to the  Touchstone  Strategic  Trust (the  "Trust"),  a
Massachusetts   business  trust,   in  connection   with  the   above-referenced
registration  statement  on Form  N-14  (the  "Registration  Statement"),  which
relates to the Trust's shares of beneficial  interest,  without par value of the
Touchstone Diversified Small Cap Growth Fund (collectively,  the "Shares"). This
opinion is being  delivered to you in connection  with the Trust's filing of the
Registration  Statement  to be  filed  with  the U.S.  Securities  and  Exchange
Commission  (the "SEC")  pursuant to Rule 488(a) of the  Securities  Act of 1933
(the "1933 Act").  With your  permission,  all  assumptions  and  statements  of
reliance  herein  have  been  made  without  any  independent  investigation  or
verification on our part except to the extent otherwise expressly stated, and we
express no  opinion  with  respect to the  subject  matter or  accuracy  of such
assumptions or items relied upon.

In connection with this opinion, we have reviewed,  among other things, executed
copies of the following documents:

      (a)   a  certificate  of  the  Commonwealth  of  Massachusetts  as to  the
            existence  of the  Trust,  which  is  duly  authorized  and  validly
            existing under the laws of the Commonwealth of Massachusetts;

      (b)   copies of the Trust's  Agreement and Declaration of Trust and of all
            amendments and all supplements thereto (the "Declaration of Trust");

      (c)   a certificate executed by Jay S. Fitton, the Secretary of the Trust,
            certifying to and  attaching  copies of the Trust's  Declaration  of
            Trust and Amended and Restated By-Laws (the "By-Laws"),  and certain
            resolutions   adopted  by  the  Board  of   Trustees  of  the  Trust
            authorizing the issuance of the Shares; and



      (d)   a printer's proof of the Registration Statement.

In our  capacity as counsel to the Trust,  we have  examined the  originals,  or
certified,   conformed  or  reproduced  copies,  of  all  records,   agreements,
instruments  and documents as we have deemed  relevant or necessary as the basis
for the opinion hereinafter expressed. In all such examinations, we have assumed
the legal capacity of all natural persons executing  documents,  the genuineness
of all signatures, the authenticity of all original or certified copies, and the
conformity  to original or  certified  copies of all copies  submitted  to us as
conformed or reproduced copies. As to various questions of fact relevant to such
opinion,  we have relied upon, and assume the accuracy of, certificates and oral
or written statements of public officials and officers or representatives of the
Trust. We have assumed that the Registration  Statement,  as filed with the SEC,
will  be in  substantially  the  form  of the  printer's  proof  referred  to in
paragraph (d) above.

Based upon,  and subject to, the  limitations  set forth  herein,  we are of the
opinion  that the Shares,  when issued and sold in  accordance  with the Trust's
Declaration  of Trust and By-Laws,  and for the  consideration  described in the
Registration  Statement,  will be legally issued,  fully paid and non-assessable
under the laws of the Commonwealth of Massachusetts.

We  hereby  consent  to  the  filing  of  this  opinion  as an  exhibit  to  the
Registration Statement. In giving this consent, we do not concede that we are in
the category of persons  whose  consent is required  under Section 7 of the 1933
Act.

Very truly yours,

/s/ Morgan, Lewis & Bockius LLP
